In my theory the endgame was to resurrect Kier by cloning his body and forming a reconstructed psyche from secondary data, which probably isn’t the plan here.Well, they built 23 (I think) separate personalities for her and were trying to make sure that her other memories and identities wouldn't leak through. That certainly feels, to me, like they're trying to hollow people out so that the Eagans can implant their minds in other people and become functionally immortal.
So not clones, but adjacent enough, given that the end goal is probably the same.
I honestly don’t know what the endgame here is, except maybe develop severing for more commercial options than just work (like going to the dentist), like the birthing cabin. I can’t see that working out well:
